First off I hope your wife feels better and her health improves.
I agree with Bella, go to the dealer and get a brochure on the Husqvarna embroidery machine. Give her either a gift certificate or a blank check so she can pick out the machine she wants.
Buying locally will allow her to go to the dealer for lessons on how to use the machine.
Like Butterfly says don't necessarily make it contingent on trading in her current machine, she may not want to. But if she does all the better.I love this machine, the top of the line can connect to your computer and she can download embroidery designs from the internet.
You are a jewel to do this for her. WTG Santa, I mean Guy!!!
